Description

Technical Field

[0001] The invention belongs to the technical field of pear paste production, in particular to a pear juice pressing device for pear paste production. Background Art

[0002] Pear paste is a traditional health drink made from pear juice, honey and other ingredients. It is also called snow pear paste and autumn pear paste. The production process of pear paste requires washing, core removal, crushing, juicing, and boiling the pears. The traditional juicing process is to pass the pears through a squeezing roller and then through a filter to separate the pear residue and pear juice.

[0003] For example, the utility model with the publication number CN216255271U discloses a pear juice extracting device for pear paste production, which relates to the technical field of pear paste production, including a chassis, a filtering device, an extruding device, a core removing device, a telescopic rod and a pressing plate; the upper surface of the chassis is open, and a side opening is arranged on one side of the chassis in the horizontal direction; a supporting leg is arranged at the bottom of the chassis; a discharge pipe is arranged at the bottom of the chassis, and the discharge pipe is connected to the chassis; a filtering device is arranged in the chassis, and the filtering device is located in the side opening; an extruding device is arranged on the inner wall of the chassis, and the extruding device is located above the filtering device; a support frame is arranged on the upper part of both sides of the chassis in the horizontal direction, and the support frame is a gantry structure; a telescopic rod is arranged at the bottom of the support frame; a pressing plate is arranged at the bottom end of the telescopic rod, and a plurality of through holes are evenly arranged on the pressing plate; a core removing device is arranged on the inner wall of the chassis, and the core removing device is located above the extruding device, and the core removing device is located below the pressing plate. The utility model can easily remove the core of the pear, is simple to operate, saves time and effort, and greatly improves the taste of the pear paste.

[0004] When the above-mentioned device squeezes the juice from the pears, the pulp is squeezed by the pressing roller and the juice in the pulp is squeezed out. However, due to the high content of pectin and polysaccharides in the pear pulp, the pectin and polysaccharide substances are continuously released during the squeezing process, thereby increasing the viscosity of the pear pulp, making it easy for the pear pulp to adhere to the squeezing chamber or the pressing roller, resulting in an uneven surface of the pressing roller, resulting in gaps during the later squeezing, affecting the squeezing efficiency. At the same time, the position of the pressing roller is relatively fixed, making it difficult to squeeze pears of different sizes, resulting in uneven pressure distribution during squeezing.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention facilitates the rapid cleaning of the pressing rollers by arranging the cooperation of structures such as the pressing area, the placement area and the cleaning mechanism. The pears to be squeezed are cut into pieces and poured into the pressing area. The pears are squeezed by driving the plurality of pressing rollers to rotate using a control motor. The pear residues and juice after the squeezing simultaneously enter the pressing area in the working box and are then discharged and filtered through the discharge port. After the pear juice is discharged, in order to prevent a large amount of pear residues from adhering to the surface of the pressing roller, the partition can be manually pulled out of the sleeve plate, so that the pressing area and the placement area are in a connected state. At this time, the cleaning mechanism is used The mechanism realizes the cleaning of the pressing roller. First, multiple scrapers are moved to the position directly below the pressing roller, and the driving component is used to drive the multiple scrapers to rise synchronously to press against the pressing roller, and then the pressing roller is started to rotate. During the rotation, the scrapers and the outer wall of the pressing roller rotate to scrape off impurities on the surface. The scraped impurities continue to fall inside the pressing area and are discharged through the discharge port, thereby completing the rapid cleaning of the pressing roller, solving the problem that in the existing pear juice pressing device, due to the characteristics of the pears themselves, the pears are more sticky and easily adhere to the surface of the pressing plate, resulting in an uneven surface of the pressing plate and low pressing efficiency.

[0023] The present invention facilitates the adjustment of the scraper position by arranging the cooperation of structures such as sliding rods, pulleys and driving blocks. The adjustment of the scraper position is achieved through the coordinated use of driving components, movable arms and electric push rods. When cleaning is required, the movable arm is first pushed by the electric push rod to move it to the inside of the pressing area. At this time, the driving block is driven by the electric cylinder to slide along the inside of the movable arm. Since the driving block is trapezoidal in shape and the slide groove is synchronously trapezoidal in shape and contacts the pulley, when the highest point of the driving block abuts the pulley, it will drive the top limit plate and the sliding rod to move upward synchronously, so that the sliding rod slides along the sleeve, thereby driving the top bottom plate and the center plate to move, thereby driving the top multiple scrapers to move upward synchronously to abut the pressure roller for scraping and cleaning.

[0024] The present invention facilitates the reasonable storage of the scraper by arranging a bidirectional screw and an adjusting motor and other structures. The bidirectional screw is driven to rotate by the adjusting motor. Since the threads on both sides of the bidirectional screw are opposite, the adjusting plates on both sides can be driven to synchronously approach or move away from the center plate during the rotation, thereby driving the retraction frame to retract or extend, thereby making the scrapers on both sides synchronously approach or move away from the scraper at the center. When cleaning is needed, they can be unfolded, and when storage is needed, they can be retracted. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figures 1 to 10 As shown, the present invention provides a pear juice pressing device for pear paste production, comprising a working box 1, a control panel 11 arranged on the working box 1, a moving groove 15 opened on the inner wall of the working box 1, and further comprising:

[0038] A sleeve plate 12, which is fixedly installed at the inner center of the working box 1, and a partition plate 13 is slidably arranged on the sleeve plate 12, and the partition plate 13 divides the working box 1 into a pressing area 2 and a placement area 3;

[0039] The pressing area 2 includes a plurality of pressing rollers 21 arranged in a linear array, a control motor 22 fixedly arranged at the center of the plurality of pressing rollers 21, and a moving plate 23 slidably arranged inside the moving groove 15 and rotatably connected to the center of the pressing rollers 21, and a discharge port 14 is fixedly arranged at the bottom of the pressing area 2;

[0040] A cleaning mechanism 4 for cleaning the surface of the pressure roller 21 is provided inside the placement area 3;

[0041] Among them, the cleaning mechanism 4 includes multiple scrapers 41, a retraction frame 42 hinged at the bottom of the multiple scrapers 41, a center plate 43 fixedly set on the scraper 41 at the center position, an adjustment plate 44 fixedly installed at the hinge of two retraction frames 42, and a driving assembly 45 arranged inside the working box 1 and used to drive the scraper 41 to approach the pressure roller 21.

[0042] The above scheme is adopted: when in use, the pears to be squeezed are cut into pieces and poured into the squeezing area 2, and the pears are squeezed by driving the control motor 22 to rotate the multiple pressing rollers 21, and the pear residues and juice after squeezing are synchronously entered into the squeezing area 2 in the working box 1, and then discharged and filtered through the discharge port 14. After the pear juice is discharged, in order to avoid a lot of pear residues adhering to the surface of the pressing roller 21, the partition 13 can be manually pulled out from the sleeve plate 12, so that the squeezing area 2 and the placement area 3 are in a connected state. At this time, the cleaning mechanism 4 is used to clean the pressing roller 21, and the multiple scrapers 41 are first moved to the position directly below the pressing roller 21, and the driving assembly 45 is used to drive the multiple scrapers 41 to rise synchronously against the pressing roller 21, and then the pressing roller 21 is started to rotate. During the rotation, the scrapers 41 rotate with the outer wall of the pressing roller 21 to scrape off impurities on the surface, and the scraped impurities continue to fall inside the squeezing area 2 and are discharged through the discharge port 14, thereby completing the rapid cleaning of the pressing roller 21.

[0043] like Figures 7 to 10 As shown, the driving assembly 45 includes a bottom plate 451 fixedly arranged at the bottom of the center plate 43, a sliding rod 452 fixedly arranged at the center of the bottom of the bottom plate 451, a sleeve 453 slidably sleeved on the outside of the sliding rod 452, a limit plate 4521 fixedly arranged at the bottom of the sliding rod 452, a spring 454 whose two ends are respectively fixedly connected to the sleeve 453 and the limit plate 4521, a pulley 455 arranged at the bottom of the limit plate 4521, a moving arm 457 slidably arranged at the bottom of the working box 1, and a driving block 456 slidably arranged on the moving arm 457 for driving the sliding rod 452 to slide along the sleeve 453;

[0044] The driving block 456 is trapezoidal in shape and has a relatively smooth surface. A slide groove 4561 is provided at the center of the driving block 456. The pulley 455 slides along the slide groove 4561. An electric cylinder 458 is fixedly connected to one side of the driving block 456. The side of the electric cylinder 458 away from the driving block 456 is fixedly connected to the side wall of the movable arm 457.

[0045] The above scheme is adopted: the position of the scraper 41 is adjusted by the coordinated use of the driving assembly 45, the moving arm 457 and the electric push rod 47. When cleaning is required, the moving arm 457 is first pushed by the electric push rod 47 to move it to the inside of the pressing area 2. At this time, the driving block 456 is driven by the electric cylinder 458 to slide along the inside of the moving arm 457. Since the driving block 456 is in a trapezoidal shape, and the slide groove 4561 is synchronously in a trapezoidal shape and contacts the pulley 455, when the highest point of the driving block 456 abuts the pulley 455, it will drive the top limit plate 4521 and the slide rod 452 to move upward synchronously, so that the slide rod 452 moves along The sleeve 453 slides, thereby driving the top bottom plate 451 and the center plate 43 to move, thereby driving the top multiple scrapers 41 to move up synchronously against the pressure roller 21 for scraping and cleaning. When cleaning is completed, when the lowest point of the driving block 456 abuts against the pulley 455, it will drive the top limit plate 4521 and the slide bar 452 to move downward synchronously, so that the slide bar 452 slides down along the sleeve 453, thereby driving the top bottom plate 451 and the center plate 43 to move downward, thereby causing the top multiple scrapers 41 to move downward synchronously away from the pressure roller 21, thereby facilitating the use of the electric push rod 47 to move the entire device to the placement area 3 for storage, so as to facilitate subsequent squeezing.

[0046] like Fig. 9 As shown, a storage assembly 46 for driving the retractable frame 42 to automatically retract is provided on the center plate 43, and the storage assembly 46 is located above the moving arm 457;

[0047] The storage assembly 46 includes a bidirectional screw 461 screwed on two adjustment plates 44 and rotatably connected to the center plate 43, a support plate 463 fixedly arranged on the side of the movable arm 457 and rotatably connected to one end of the bidirectional screw 461, and an adjustment motor 462 fixedly arranged on the support plate 463 and fixedly connected to the bidirectional screw 461. The threads on both sides of the bidirectional screw 461 are opposite. An electric push rod 47 is fixedly connected to the center of the inner wall of the placement area 3. The side of the electric push rod 47 away from the placement area 3 is fixedly connected to the movable arm 457. A vertical plate 16 is fixedly arranged on the side of the inner wall of the pressing area 2 away from the control motor 22. A vertical groove 161 is opened at the center of the vertical plate 16, and the vertical plate 16 is U-shaped.

[0048] The above scheme is adopted: by utilizing the storage assembly 46 to realize the extension and contraction of multiple scrapers 41, so as to facilitate quick storage, and utilizing the adjusting motor 462 to drive the bidirectional screw 461 to rotate. Since the threads on both sides of the bidirectional screw 461 are opposite, during the rotation process, the adjusting plates 44 on both sides can be driven to synchronously approach or move away from the center plate 43, thereby driving the contraction frame 42 to contract or extend, thereby making the scrapers 41 on both sides synchronously approach or move away from the scraper 41 at the center. When cleaning is needed, they can be unfolded, and when storage is needed, they can be retracted.

[0049] like Figures 3 to 5 As shown, a circular clamp block 211 is fixedly connected to the center of the side of the multiple pressure rollers 21 away from the control motor 22, and a clamp ring 212 is rotatably connected to the side of the multiple circular clamp blocks 211 away from the pressure roller 21. An adjustment mechanism 24 for driving the spacing adjustment of the multiple clamp rings 212 is provided on the vertical plate 16;

[0050] The adjusting mechanism 24 includes a driving plate 241 slidably set on the vertical plate 16, a plurality of driving grooves 242 arranged in an umbrella shape on the driving plate 241, a clamping column 243 clamped in the plurality of driving grooves 242 and fixedly connected to the side of the clamping ring 212 away from the annular clamping block 211, a sliding block 244 fixedly set on the side of the driving plate 241 away from the clamping ring 212 and slidably connected to the vertical groove 161, a driving screw 245 screwed on the sliding block 244 and rotatably connected to the vertical plate 16, and a rotating plate fixedly set on the top of the driving screw 245.

[0051] The above scheme is adopted: by utilizing the adjustment mechanism 24 to realize the control of different squeezing conditions, the sliding block 244 is driven to slide along the vertical groove 161 by rotating the rotating plate, and then the driving plate 241 is driven to slide up and down along the vertical plate 16. Since the driving groove 242 opened on the driving plate 241 is dense at the top and scattered at the bottom, when it moves upward, it can drive the clamping columns 243 to approach each other, and when it moves downward, it can drive the clamping columns 243 to move away from each other, thereby driving multiple clamping rings 212 and annular clamping blocks 211 to approach or move away from each other, so as to achieve the effect of reasonably adjusting the distance between the pressing rollers 21 and realize the squeezing of pear blocks of different sizes.

[0052] The working principle and use process of the present invention are as follows: when using the device, the pears are cut into pieces and poured into the pressing area 2, and the control motor 22 is used to drive the multiple pressing rollers 21 to rotate to squeeze the pears. The pear residue and juice after squeezing synchronously enter the pressing area 2 in the working box 1, and then are discharged and filtered through the discharge port 14. After discharge, the partition plate 13 is manually pulled out from the sleeve plate 12, so that the pressing area 2 and the placement area 3 are in a connected state. At this time, the electric push rod 47 is first used to push the moving arm 457 to move it into the pressing area 2, and the adjusting motor 462 is used to drive the bidirectional screw 461 to rotate. Since the threads on both sides of the bidirectional screw 461 are opposite, the adjusting plates 4 on both sides can be driven during the rotation process. 4 synchronously approaches the center plate 43, thereby driving the retracting frame 42 to stretch, so that the scrapers 41 on both sides synchronously move away from the scraper 41 at the center and unfold it, and drive the driving block 456 to slide along the inside of the moving arm 457 by using the electric cylinder 458. Since the driving block 456 is in a trapezoidal shape, and the slide groove 4561 is synchronously in a trapezoidal shape and contacts the pulley 455, when the highest point of the driving block 456 abuts the pulley 455, it will drive the top limit plate 4521 and the slide bar 452 to move upward synchronously, so that the slide bar 452 slides along the sleeve 453, thereby driving the top bottom plate 451 and the center plate 43 to move, thereby driving the top multiple scrapers 41 to move upward synchronously to abut against the pressure roller 21 for scraping and cleaning.
